Carbon dioxide (CO2) has been the subject of media attention of a different kind recently, with various statements circulating about its potential as an automotive air conditioning refrigerant.

Gasworld understands that a recent press statement from Germany claims ‘CO2 is the right refrigerant’.

In response to that statement, SAE International President Frank O. Klegon has invited all automobile manufacturers to join in an industry collaborative effort to fully evaluate the technical aspects of the use of CO2 as an automotive air conditioning refrigerant.

SAE International, a global association of more than 133,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries, has expertise in the research, analysis and application of a variety of automotive refrigerants.

In the last decade, more than 10 major SAE Cooperative Research Program (CRP) projects have provided forums for subject matter experts from around the industry to meet, discuss and agree on advantages and disadvantages of various alternative refrigerants, as well as the management of accompanying risks.

Klegon said in a statement, “The implementation of CO2 as an automotive refrigerant is not without technical challenges.”

The US Environmental Protection Agency (EPA) has published its concerns regarding the use of CO2 as a mobile air conditioning refrigerant for passenger cars.
